Description

Detailed description of the invention

The present invention relates to an electric fence that is repelled by installing a conductive net around the field and applying shock high voltage to the conductive part to cause electric shock to harmful beasts such as monkeys, foxes and hakubishin. It is.

In recent years, in the fields of mountainous areas, damage caused by invading beasts such as monkeys, rabbits, and hakubishin has frequently occurred. Therefore, electric fences have been installed around the crops in the fields. As shown in FIG. 1, this electric fence is made of an insulating band 2 b made of a stranded wire made of an insulating material and a metal made of an insulating material by an insulating column 1 erected on the ground surface at intervals of several meters. An electric fence net 2 in which conductive bands 2a made by twisted wires are alternately arranged is stretched around the field, and the conductive band 2a generates 6,000V to 7, An impact high pressure of 000 V is applied.

The conventional electric fence has the following problems.
(1) For safety considerations on the human body, the high voltage applied to the conductive part is applied intermittently rather than continuously. For this reason, monkeys with excellent athletic ability climb over the electric fence net 2 without electric shock during about 1 second of de-energization.
(2) Since the pole 1 is easier to grip than the electric fence net 2 which is easy to bend, the monkey grabs the pole 1 and climbs over the electric fence without electric shock during non-energization.
(3) Since the monkey climbs the electric fence net 2 to get an electric shock, the height of the electric fence net 2 must be 2m or more, the maximum height that an adult monkey can jump and reach. Installation of an electric fence is difficult.

Therefore, the problem to be solved by the present invention is to provide an electric fence that is easy to install because it works even if the monkey is lower than the conventional electric fence, although it is difficult for monkeys to get over in a short time. is there.

As shown in the front view of FIG. 2 and the cross-sectional view of FIG. 4, an electric fence was constructed as follows. Hereinafter, this method will be referred to as a “wire mesh method” in this specification.
(11) An insulating support post 1 erected on the ground surface at intervals of several meters, the uppermost portion being a conductive rope 2c, and an insulating strip 2b made of an insulating stranded wire underneath, An electric fence net 2 in which a conductive band 2a made of a stranded wire obtained by twisting a metal wire into a fiber and an insulating band 2b made of a stranded wire made of an insulator are arranged in this order is surrounded by the electric fence net 2. The column 1 is stretched so that the column 1 is positioned inside the compartment, and the lower end of the electric fence net 2 is fixed to the ground surface 9 with a fastener 4 at intervals of several tens of cm.
(12) The wire mesh 5 smaller than the “average thickness of the finger of an adult Japanese monkey's hand” is placed outside the electric fence net 2 by the support 1 from the conductive rope 2c of the electric fence net 2. An orthogonal clamp 6 or the like used for assembling the scaffolding for construction so that the upper end of the metal mesh 5 is located several tens of centimeters below and the lower end of the metal mesh 5 is located tens of centimeters above the conductive band 2a of the electric fence net 2 The upper end of the wire mesh 5 and the insulation band 2b of the electric fence net 2 and the lower end of the wire mesh 5 and the insulation band 2b of the electric fence net 2 are respectively bound with a binding band 7 or the like at intervals of several tens of centimeters. .
(13) Connect the conductive rope 2 c and conductive band 2 a of the electric fence net 2 to the plus side of the impact high-voltage power supply 3, and connect the wire mesh 5 and the ground surface 9 to the minus side of the impact high-voltage power supply 3.

As shown in the front view of FIG. 3 and the cross-sectional view of FIG. 5, a similar electric fence can be configured by using a conductive sheet 8 instead of the “mesh type” wire mesh 5. Hereinafter, this method will be referred to as a “sheet method” in this specification. The conductive sheet 8 is a sheet woven using a thread in which a metal wire is twisted into an insulating fiber. It has already been developed as a grass protection sheet for an electric fence that prevents grass from growing on the surface where the electric fence is installed and does not impede electric shock to harmful animals by the electric fence. The drawing of “sheet method” is almost the same as the drawing of “wire mesh method”. The difference from the “wire mesh method” is that a conductive sheet 8 is used instead of the wire mesh 5 and that the conductive sheet 8 is lighter and more flexible than the wire mesh 5. It can only be done with a binding band, etc. without the need.

As shown in FIG. 6, after the lower end of the electric fence net 2 reaches the ground surface 9, it is bent into an L shape so as to cover the ground surface 9 outside the section surrounded by the electric fence net 2 with a width of several tens of centimeters. One can prevent the spear and hakubishin from digging the soil and going under the electric fence.

The effects of the “wire mesh method” of the present invention are as follows.
(21) Since the strut 1 is inside the section surrounded by the wire mesh 5 smaller than the “average thickness of fingers of an adult Japanese macaque hand”, the monkey 10 outside the section You can't grab and climb.
(22) The adult monkey 10 cannot climb the wire mesh 5 smaller than the “average thickness of fingers of an adult Japanese monkey hand”. In addition, the maximum height that the adult monkey 10 can reach by jumping is 2m, and the height of the adult monkey 10 is 90cm, so even if the height of the conductive rope 2c of the electric fence net 2 is at least 1.1m or more If the allowance is higher than 1.5 m, the adult monkey 10 cannot jump over the conductive rope 2 c of the electric fence net 2. Therefore, the adult monkey 10 jumps to the wire mesh 5 and then grabs the upper end of the wire mesh 5 connected to the negative side of the impact high-voltage power supply 3 with one hand and is above the wire mesh 5 with another hand and Grasp the conductive rope 2c of the electric fence net 2 connected to the plus side and try to get over the electric fence. Alternatively, grasp the conductive rope 2c of the electric fence net 2 with both hands and try to get over the electric fence from the state where the foot is touching the wire mesh 5. However, because the mesh of the wire mesh 5 is smaller than the thickness of the toes of the adult monkey 10, the adult monkey 10 cannot grasp the wire mesh 5 with the toes, and this state continues for a while and is repulsed by electric shock. . Therefore, if the height of the conductive rope 2c of the electric fence net 2 is 1.5 m or more, it plays the role of an electric fence, and the height of the electric fence net 2 is 2 m as in the conventional electric fence in FIG. Since there is no need to make it more than this, it is easy to install an electric fence.
(23) The monkey 10 of a child with a finger thinner than “average thickness of fingers of an adult Japanese macaque hand” can grab the wire net 5 and climb. The child monkey 10 also grabs the upper end of the wire mesh 5 with one hand, grasps the conductive rope 2c of the electric fence net 2 above the wire mesh 5 with another hand, and then tries to get over the electric fence. Alternatively, grasp the conductive rope 2c of the electric fence net 2 with both hands and try to get over the electric fence from the state where the foot is touching the wire mesh 5. To do so, it takes time to insert and remove the toes into the mesh of the metal mesh 5 which is slightly larger than the thickness of the toes. Is done.
(24) Since the lower part of the wire mesh 5 is blocked by the electric fence net 2, monkeys, cages, hakubishin, etc. cannot penetrate below the wire mesh 5.

The effects of the “sheet method” of the present invention are as follows.
(31) Since the strut 1 is inside the section surrounded by the conductive sheet 8, the monkey 10 outside the section cannot grab the strut 1 and climb.
(32) The monkey 10 cannot climb the conductive sheet 8. The maximum height of the adult monkey 10 jumping and reaching is 2m, and the height of the adult monkey 10 is 90cm. Therefore, even if the height of the conductive rope 2c of the electric fence net 2 is at least 1.1m, there is a margin See 1. If it is 5 m or higher, the adult monkey 10 cannot jump over the conductive rope 2 c of the electric fence net 2. Therefore, the monkey 10 jumps to the conductive sheet 8, grasps the upper end of the conductive sheet 8 connected to the negative side of the impact high-voltage power supply 3 with one hand, and is located above the conductive sheet 8 with another hand, Grasp the conductive rope 2c of the electric fence net 2 connected to the positive side of the power supply 3, and then try to get over the electric fence. Alternatively, grasp the conductive rope 2 c of the electric fence net 2 with both hands and try to get over the electric fence from the state where the foot is in contact with the conductive sheet 8. However, since the monkey 10 cannot put the toes on the conductive sheet 8, this state continues for a while, and in the meantime, he is repulsed by electric shock. Therefore, if the height of the conductive rope 2c of the electric fence net 2 is 1.5 m or more, it plays the role of an electric fence, and the height of the electric fence net 2 is 2 m as in the conventional electric fence in FIG. Since there is no need to do more than this, it is easy to install an electric fence.
(33) Since the lower part of the conductive sheet 8 is blocked by the electric fence net 2, monkeys, rabbits, hakuubicin, etc. cannot penetrate the lower part of the conductive sheet 8.

The best mode for carrying out the present invention is as follows.
(41) Although the data of “average thickness of fingers of adult Japanese macaque hands” is not disclosed, the wire fence 5 of the electric fence is 6 mm or less, and the turtle shell wire mesh of galvanized iron wire with a wire diameter of 0.7 mm, Alternatively, a stainless steel turtle shell metal mesh with a mesh size of 6 mm or less and a wire diameter of 0.57 mm is considered appropriate.
(42) In order to fix the wire mesh 5 to the support column 1, the use of the orthogonal clamp 6 used for assembling the construction scaffold is easy to perform.
(43) The insulation band 2b at the bottom of the electric fence net 2 has a mesh size of 5 cm or less so that children's monkeys, hakubishin, etc. cannot pass through, and the thickness of the stranded wire so that it is not easily bitten by hakubishin, etc. Is preferably 5 mm or more.
